Just two more days to vote for 2012's fan-chosen inductee into the Transformers Hall of Fame! I suggest Beast Wars Megatron. The other four ain't bad either, but I'm just putting BW Megs out there.
Also, just like the Dinobot and Waspinator designs before it, you can buy a 11x17-inch "YES" poster on thick glossy cardstock! What's also available is the corresponding "YES" t-shirt! That's right, if you want to, say, proclaim your support for BW Megs while walking around BotCon, this would be a fun way to do it. (I won't have any to sell at the show itself.) (I will have the posters.)
(The Waspinator poster is sold out and I may reorder soon.)
